Nowadays, the problem of air pollution is deeply concerned by everyone, and we want to control it from the source. The application of nitrogen oxide detector is essential, it can effectively monitor nitrogen oxide emissions, thereby reducing accidents. Therefore, in view of the current nitrogen oxide monitoring standards, we should actively install nitrogen oxide online monitors to monitor nitrogen oxide emissions within the factory. What should I pay attention to when installing NOx detector ? The following is a brief introduction by yi yun Tian:

Note the following when installing the NOx detector:

1. when installing the nitrogen and nitrogen oxide detector, the instrument can be placed indoors or outdoors, vertically installed on a column or wall, and installed nearby at the sample gas sampling point, avoiding places with vibration, strong magnetic field and heat source.

2. protective measures such as dustproof, waterproof and high temperature prevention should be considered when installing the nitrogen oxide detector. the detection range of each 1 probe in the open area is 60 square meters. at the same time, factors such as gas diffusion, wind direction, temperature, humidity and regional closure should also be considered.

3. according to the specific gravity and wind direction of the gas, the nitrogen oxide detector should be installed within one meter from the place where the gas may leak, so that the actual reaction speed of the instrument is relatively fast, otherwise the concentration of combustible gas or toxic and harmful gas at the place where the nitrogen oxide detector is installed may not exceed the standard, however, the local gas at the leak point has exceeded the standard, but the detector and the host cannot alarm.

4. the nitrogen oxide detector should be installed more than 30cm from the ground to prevent water from splashing in. in general, the probe should be installed above the house or equipment to detect harmful gases with a specific gravity less than that of air. The probe should be installed close to the ground for harmful gases with a specific gravity greater than that of air. When installing, the probe should face down. If it is installed outdoors, a rain shield should be installed above the nitrogen oxide detector.

5. the nitrogen oxide detection instrument should be used within the range of -20~70 ℃ (uncondensed) and 0 ~ 85% RH respectively at temperature and relative humidity, so that the nitrogen oxide detection instrument can exert good performance and the service life of the instrument can be prolonged. If the nitrogen oxide detector is exposed to corrosive substances, it may damage the materials and parts of the instrument and reduce the service life of the instrument, so it should be avoided.

In summary, there are some aspects that should be paid attention to when installing the nitrogen oxide detector.The correct installation of the nitrogen oxide detector can not only make the instrument always in normal working condition, but also effectively extend the service life of the instrument, so that the nitrogen oxide detector can be widely used in petroleum and petrochemical, chemical plants, smelters, iron and steel plants, coal plants, thermal power plants, pharmaceutical research, pharmaceutical production workshops, tobacco companies, environmental testing, school research, building construction, fire alarm, sewage treatment, industrial gas process control, boiler room, garbage treatment plant, tunnel construction, oil pipeline, gas station, underground gas pipeline maintenance, indoor air quality testing safety protection in dangerous places, aerospace and other fields.
